<< 9/12 < > Chandra observations of a region of the Galactic Center have found an X-ray filament and cloud about 40 light years across (blue). These X-ray features are associated with large filamentary and shell-like structures that are bright sources of radio waves (red). The X-ray emission is thought to be produced when energetic electrons from the radio filaments collide with a cloud of cold gas that has a mass one million times the mass of the sun. This process of the bombardment of cold gas clouds with energetic electrons could explain the origin of the mysterious X-ray ridge along the plane of the galaxy that was discovered nearly 30 years ago.
